Four Season Roof Rack (If equipped)
Always load your luggage as far back as it will safely go on the
four season roof rack. Do not load more than 100 lb. (45 kg).
Be careful that your vehicle does not exceed the Gross Vehicle
Weight Rating (GVWR) or its Gross Axle Weight Rating (GAWR
front and rear). The GVWR and GAWR are located on the
Safety Compliance Certification Label (located on the driver's
door pillar).
The four season roof rack
The front and rear cross-bars can be adjusted forward and
backward. Place your luggage between the bars, adjust the bars,
and secure the luggage with rope to the bars. There are also
adjustable loops on the side bars for the rope attachment.
WARNING
Be sure that items on the roof rack are securely fastened.
